Windows update.

Have had windows 8.1 for a couple of weeks since then windows update just hangs on checking for updates, can't change lock screen wallpaper and after a few hours of use the stylus stops working properly. Until I restart cannot use it. Should have stayed with windows 8.

I am having similar errors. I have done both the "built-in" Windows Update troubleshooter which is located in Control Panel, as well as, used the diagnostic tool available on Microsofts website. Both options indicate that they found the "errors" and "fixed" them....however, I still cannot use Windows Update. It just hangs while trying to connect....
